Specification of Letters Patent.

Patented April 3, 1906.

Application filed March 20,1905. Serial No. 251,030.

To all whom it may concern:

Be it known that I, WARREN E. Know, a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsyl- Vania, have invented certain new and useful Improvements in Button Blank Grinding and Feeding Machines; and I do hereby declare the following to be a full, clear, and eX- act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, forming part of this specification.

This invention relates to button blank grinding and feeding machines, and has for its object the production of a mechanism to which button-blanks are fed and thereafter one side of the blank is ground and the blank then automatically turned over and delivered to the chucks of a button-machine associated therewith.

The features of this invention are hereinafter set forth and described, and illustrated in the accompanying drawings, in which Figure 1 is a top or plan view of mechanism embodying my invention, together with parts of a button-machine. Fig. 2 is a view in elevation of the same. Fig. 3 is a sectional detail on the line as a: in Figs. 1- and 2.

In the drawings illustrating my invention, A is the framework of my improved machine, and B a portion of the framework of a button-machine associated therewith, which latter machine, however, forms no part of my invention.

In my improved machine,'C is a table adjustably secured to the top of the frame A, so that it can be raised or lowered, as desired. One edge of this table C is cut away, so as to leave a ledge C extending from the upper surface thereof and terminating in a radial shoulder or edge a, as and for the urpose hereinafter set forth. On the top of the table C there is mounted a rotating disk D, driven by a vertical shaft E, and above one side of the disk D there is mounted a grinding-wheel F,- suitably incased and provided with a suction-pipe This rinding-wheel F is preferably driven by a belt (not shown) operating on a pulley F on the shaft F thereof.

Around the periphery of the disk D there is a row of holes (I of suitable size to receive buttonblanks d to be inserted bottom side up therein, and as the disk D is rotated by the shaft E in the direction of the arrow the blanks so inserted are carried under the grinding-wheel F and faced off and carried onward.

Under the edge of the disk D there is a circular table II, adjustably secured on a vertical post G, extending upward from the frame A. Loosely mounted on the post G and rotating on the table H there is a disk I. The edge of the disk I revolves under the ledge C of the table C, preferably in the opposite direction than the disk Drevolves, and has around. its periphery a row of holes 11 of suitable size to receivelbutton-blanks, and the revolutions of the disks D and I are so timed that the button-blank holes 1' in the disk I are just in front of the edge of the ledge O at the time the button-blanks d in the, holes (1 of the disk D tip over the front edge of the ledge C, the continuous forward movement ofthe disk D operating on the button-blanks d to turn them over, so that they drop into the holes 71 in the disk I the other side up, as illustrated in Fig. 3, this operation being facilitated by the movement of the disk I in the opposite direction from that of the disk D. The periphery of the disk I is also provided with ratchet-teeth i, adapted to be engaged by a dog mechanism J J, which is in termittently actuated by arms K on the part L of a button-machine mechanism associated with my improved machine, which dog mechanism operates to actuate the disk I inter mittently in the direction of the arrow, so as to bring the openings t therein consecutively under, the openings d of the continuouslymoving disk D, and as each blank d passes off of the edge 0 of the ledge C of the table C the front edge Will turn downward and the blank 01 will turn over the other side up, as illustrated in Fig. 3, and fall into the openings '5 in the disk I. The disk I in its intermittent travel then carries the blank around over the table II and over the upper ends of the traveling chucks M of the associated button-machine and delivers one blank to each chuck M, with the side thereof up which it is desired to finish. adapted to be connected. so as to operate in unison in any suitable manner 5 but I have These two machines are the holes i ofthe disk I, which disk I carries them onward and automatically delivers them consecutively to the traveling chucks M of an associated button-machine.

I have herein described a convenient mechanism for automatically turning over buttonblanks during the process of feeding them to a button-finishing machine. I do not, however, limit myself to the exact mechanism herein shown and described therefor, as many modifications of said mechanism can readily be made by those skilled in the art to which my invention appertains without departing from the spirit of my invention.

Having thus described my invention, so as to enable others to construct and utilize the same, what I claim as new, and desire to secure by Letters Patent of the United States, 1s

1. The combination in a button.blankfeeding machine, of mechanism for finishing the backs of button-blanks, mechanism for moving button-blanks to and past said finishing mechanism, receiving and delivering mechanism adapted to receive and'deliver buttonblanks into the open chucks of an associate button-finishing machine with their finished backs down, and actuating mechanism adapted to operate the said mechanisms synchronically with each other and with the chucks of an associate button-finishing machine, substantially as set forth.

2.
